"NFS server servername not responding still trying"

Sounds like your Server is mounting a filesystem from another server. The server "servername" seem not to respond. On the server "servername" try to stop and start the nfs.server:

/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.server start

Also you may want to stop and start the nfs client on your system

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.client start

Check for any warning or errormessage.

Hope this helps. Stefan

Hi,

You are right the problem is with not responding nfs server, but before stopping nfs, try the following:

1. Check /etc/fstab if there are some records for mounting nfs file systems. If so, you can next check which nfs server does not respond and comment respective lines, at least until server start to work again.

2. Check automounter maps. May be automounter is trying to mount a remote nfs file system whereas the server does not respond.

The first reason is more probable.

Hope this helps.
Rgds.

hi, bala

carry out the steps given by steph, if still getting the same error, it is purely the network problem, that u r server couldn't reach the NFS server. so check for the network config

is your server called servername!?
You might want to add servername to the /etc/hosts or just make sure you can nslookup/ping it.

Later,
Bill

I sounds like your system is trying to mount an NFS filesystem that is not available.
You might try to edit the /etc/fstab file and enter # in front of the line item that is in error. This will comment out this line and will make the fs unavailable for mounting. If this is a FS that must be mounted, then try typing in showmount -e to verify that the server is exporting this fs to you properly. If not you will have to follow up with the Sys Admin in the exporting server.

Try "mount -a" and see if it hangs on something. Also, are you running automounter or autofs? If so, you may have a problem with the configuration, or if you've killed automount while something was mounted, this will cause the same problem and requires a reboot.

Hi Bala
It looks as if you have mounted a CD using pfs_mount and unmounted using a umount command . If yes then try to grep on pfs and kill the processes in the lower to higher order . then try bdf if still it doesnt work then the only way left is to boot the machine. Though this will not interfere in the operations it would definatley not let you run bdf or any such like commands .
